“…According to the results in Table 3, soil pH on the ZFP appeared suitable for crop production, though there was a significant difference among the land types. U showed significantly lower eCEC than other land types and Lds had the highest content among the others, which was consistent with the findings obtained by Buri et al (1999). Dobermann and Fairhurst (2000) showed that S deficiency for rice plants occurs when the concentration is less than 9 mg kg -1…”

“…Effective CEC is one of the indicators for evaluating soil fertility in the floodplains of West Africa (Buri et al 1999) and an examination of correlation coefficients with other parameters explains a degree of weathering of soil in the study area. According to the analysis results of correlation in Table 4, eCEC showed a significant (P<0.01) correlation with clay content and T-C. As Bationo and Buerkert (2001) showed, soil with kaolinite predominantly as the clay mineral had a low capacity of cation exchange, and organic carbon played an important role in improving that capacity.…”

This study aimed to identify suitable areas for rice cultivation by evaluating the soil characteristics of underdeveloped land in Sub-Saharan Africa. Two transect lines were set on the Zaw floodplain (ZFP) along the White Volta River in the Northern Region of Ghana for a detailed survey on land types and soil sampling. Land types identified along the transect lines were upland (U), lowland grass (Lg), lowland shallow swamp (Lss), and lowland deep swamp (Lds). The soil texture for U, Lg, and Lss was classified as silt loam (SiL), while Lds was classified as silty clay loam (SiCL). Soil pH (H2O) was above 6 for U and Lg, and below 6 for Lss and Lds. Extractable S and available Zn were significantly greater in Lds than in other land types. Available Cu, Mn, Ni, and total nitrogen (T-N) were significantly lower in U, and total carbon (T-C) was significantly greater in Lds than in other land types. Factor analysis indicated that Lds had better soil fertility and sulfur availability than other land types. However, it seemed unsuitable for rice production due to deep water depth during the rainy season. Although Lss seemed to be relatively less suitable than Lds due to low soil fertility and low sulfur availability, the water depth in Lss was not as deep as in Lds. Access to a water source was easier in Lss than in Lg; thus, the Lss land type was considered comparatively suitable land for rice production in the study area. Nevertheless, the result implies that soil fertility and sulfur could be constraints, thereby requiring the proper application of fertilizer.Discipline: Watershed and regional resources management Additional key words: Soil fertility, sulfur deficiency, food security, Tamale

“…It is important to state that even though Toure et al (2009) documented the importance of toposequence in the hydrology and drainage of the inland valley ecosystems of West Africa. However, most of the available research information about soil conditions in the West African inland valleys focused mainly on fertility and/or pedo-mineralogy (Issaka et al, 1996(Issaka et al, , 1997Buri et al, 1999Buri et al, , 2000Annan-Afful et al, 2004, 2005Abe et al, 2006Abe et al, , 2007Abe et al, , 2009Udo et al, 2009). The physical aspect has been sparingly studied, with little or no emphasis on the effects of topography (Annan-Afful et al, 2004;Abe et al, 2009) Thus, the objective of the study was to examine how some selected soil physico-chemical properties varies and among landscape positions at a sawah site.…”

A study was conducted at a sawah site in Ghana to examine the relationship between landscape position and some selected soil properties with the aim of generating adequate data for modeling landscape relationships and to aid both researchers and farmers in taking critical management decisions. Soil properties namely total porosity, moisture content, infiltration rates, hydraulic conductivity, sand content, silt content, clay content, gravel concentration, bulk density, soil pH, total nitrogen, soil organic matter and cation exchange capacity were collected and analysed. Data were collected at the foot slopes, middle slopes and at the upper slopes from four major landuses (maize, oil palm, natural vegetation and plantain) in the study area. Simple statistical parameters such as mean and standard deviation were used to analyse the data. Moisture content, total porosity, soil pH, organic matter and carbon and total nitrogen increased downslope whilst sand content, clay content, bulk density occurred at upper slopes decreased downslope. Management practices appeared to have influenced infiltration rate, hydraulic conductivity and silt content.

“…1). The locations are spread over the given four agro-ecological zones, whereas data on the SuS and SaS zones are combined, because the number of samples collected in these two zones are limited and their data sets generally show similar mean values [see Issaka et al (1997) and Buri et al (1999;2000)] 9,10,22 . These sampling sites include both potentially reclaimable and actually cultivated soils for rice and other crops [see Issaka (1997) and Buri (1999) General fertility characteristics and soil classification 1.…”

In this paper, we review the soil fertility characteristics and the nature of material in the West African lowlands in comparison with paddy soils in tropical Asia to examine their potential for rice cultivation. Soil samples collected from major lowland ecosystems, i.e., inland valleys (185 locations) and flood plains (62 locations), in 13 countries (Benin, Burkina Faso, Cameroon, Cote d'Ivoire, Ghana, Guinea, Niger, Nigeria, Liberia, Mali, Senegal, Sierra Leone, and Togo) generally show low values of pH, total C and N, available (Bary-2) P, exchangeable Ca and Mg, effective cation exchange capacity (ECEC), and clay content. These properties of the 87 topsoil samples selected from 247 collected samples are well associated with mineralogical composition. The clay and primary minerals predominantly consist of kaolinite and quartz, respectively, which suggests that the lowland soils in the region have low nutrient-holding capacity and a limited potential for inherent nutrient supply. In general, soil pH, available P, exchangeable bases (Ca, Mg, K, and Na), and ECEC decrease while total C, total N and exchange acidity (Al and H) increase with increasing rainfall. This tendency is mostly explained by the enhanced biomass production and soil weathering sequence governed by the climate. In terms of rice production, the lowland soils in West Africa have lower values of general fertility parameters and poorer mineralogical characteristics compared to paddy soils in tropical Asia, which includes Bangladesh, Cambodia, India, Indonesia, Malaysia, Myanmar, Philippines, Sri Lanka, and Thailand. In addition, deficit levels of S and Zn for rice production are widely observed in the lowland soils in West Africa. These findings suggest that soil fertility characteristics show substantially less potential for rice production in West Africa than in tropical Asia.Discipline: Soils, fertilizers and plant nutrition Additional key words: agro-ecological zones, flood plains, inland valleys, mineralogical composition, sulfur and zinc deficiencyThe present paper is a joint contribution from the projects 'Development of Sustainable Rice Farming Systems in Low Activity Clay
